Hey! Okay, that clears it up then. It's definitely a cleaner way to set that up. Then I suppose the other mod does some kind of subtraction of time so when "doDaylightCycle_tc" is turned off it rewinds time. I see I see. I used to set something up with a command block clock that would progress time slowly with the gamerule turned off. So that makes sense now. I suppose I could set up a Redstone/command clock that checks for players online and only adds time when it detects players and keep the gamerule off. Having an option to slow time down along with this mod would be very helpful and more efficient since it's already watching for players to come on or offline. I'm not sure how TimeControl <https://www.curseforge.com/minecraft/mc-mods/time-control> did it but it seemed to be fairly robust whereas "longer days" seems to just subtract a fraction of ticks. (Your answer cleared that up.) Thanks for the response! I'm on 1.12.2 because of Rl Craft. The days feel too short, so on this server with a couple of friends, I like the days a bit longer. This is also why I wanted to stop time so that we don't wake up in other seasons/nighttime/daytime and also run up the days? Etc. Though serene does offer a config option to stop seasons when no one is online, not for days howver. Thank you very much for taking the time to respond! It helped me out a lot!
